Wireless Temperature Sensor

Product Description

The Wireless Temperature Sensor is now all digital, replacing the original Wireless Temperature Sensor

Wireless temperature sensor now uses a Dallas 18B20 1-wire digital sensor with accuracy of ±.5°C accuracy. The sensor still operates at a very low power and can last up to a year on a single CR2032 coin cell battery when configured to send readings every 10 minutes.

Installation

Install battery and close enclosure as described here.
